USAMS US-CD92 PD power bank

USAMS US-CD92 PD power bank

The power bank was charging.
At the moment of switching the voltage on the UM25C tester, it determined the protocol as WC3.0, but in the photographs ( when 9 and 12V were selected) the protocol was listed as "unknown". Photographs of the current strength through the magnetic and two simple wires. If you connect to testers at both ends of this network (to track readings), then charging did not go on. I have used USAMS wires for a long time. Replacing the port, I found out, will cost from 500 to 1000 rubles, but with such a price, the repair of the port does not shine 🙂 The power bank itself practically costs like the upper price of the Type-C replacement interval. On magnets, the current is always less. Charging the phone for a long time did not work, but we managed to get the power bank to charge through the Type-C port When I had testers and a load, I began to take a more reasonable approach to checking goods from AliExpress. Through it, the current strength increased.
Perhaps he broke it himself or sent a defective product. We loaded 3A and the bank withstood both 9V / 2.0A and 12V / 1.5A: These were my first wires from AliExpress. As noted in the comments, the reason for the port not working may be precisely in the chip, but with additional research and the banal pressing of a prominent loose contact in the port, I managed to force it to charge/s through the USB-C port, but the joy was not long.
The magnetic wire (1.2 m) showed the smallest current strength of the three cables.
And the third wire, also from USAMS, 0.25 m, carried https://jiji.com.gh/297-generators/yamaha current from the power bank to the phone with the highest rate. Therefore, in my case, it is better to change not the IP5328P chip at first, but the Type-C connector itself. Moreover, this is the first generation of USAMS magnetic wires.

Exactly in the same position as in the photo above: we used the TIEGEM Type-C adapter (male) to micro-USB (mother) and only in the position with the inscription down (another adapter, in which instead of micro-USB USB did not charge). The shorter the wire, the greater the current. Tests for the load of the USB-A port of the bank passed. After a long communication with the store, I was lucky to get a power bank from them at a big discount.
The tester from RD determined the supported current at 2.4A. According to the characteristics, it should be 5V / 3A.
The second wire is a 0.3m wire from Tiegem.
